The London Stock Exchange has boosted revenues in its order book business by more than 16% since March, after a strong summer of trading and the rising cash equity markets.

The total value of the LSE's order book is expected to increase by almost a third over the same period last year, according to research by Credit Suisse First Boston. The research note said: "Although there were no initial public offerings on the main market in August, activity in earlier months was extremely busy and we expect a strong pipeline of activity into the second half."
